(-1/125)^2/3-1/3log的底数1/2(1/27)*log的底数3(1/32)+4^(-1+log的底数4(2004))

比较log(1/2)0.3,log(3)0.2的大小 [log(4)3+log(8)3][log(3)2+log(9)2]-log(1/2)32∧1/4过程详细点,log(4)3是log以4为底3的对数， log(2)3乘log(3)4乘log(4)5乘og(5)2↓这个为准log(2)3乘log(3)4乘log(4)5乘log(5)2 1楼不的懂 关于数学对数的换底公式推论的问题已知 log(2)(3) = a,log(3(7)=b,用a,b表示log(42)(56)因为log(2)(3)=a,则1/a=log(3)(2),又∵log(3)(7)=b,∴log(42)(56)=log(3)(56)/log(3)(42)=log(3)(7)+3·log(3)(2)/log(3)(7)+log(3)(2)+1=ab+3/ab+b+1 关于数学对数的换底公式推论的问题已知 log(2)(3) = a,log(3(7)=b,用a,b表示log(42)(56)因为log(2)(3)=a,则1/a=log(3)(2),又∵log(3)(7)=b,∴log(42)(56)=log(3)(56)/log(3)(42)=log(3)(7)+3·log(3)(2)/log(3)(7)+log(3)(2)+1=ab+3/ab+b+1 (-1/125)^2/3-1/3log的底数1/2(1/27)*log的底数3(1/32)+4^(-1+log的底数4(2004)) 2log(5 ) 25+3log(2) 64-8log(2) 1 ( )内代表的是以什么为底 2log(5 ) 25+3log(2) 64-8log(2) 1 ( )内代表的是以什么为底 log底数7[log底数3（log底数2X）]=0,那么x^1/2的值是 化简2log`5(10)+log`3(0.25）+log`1/5(125)=(2) log`2(根号2）+log`9(27）+（1/4)^log`4(1/16) 注意 `为下角标 试解关于x的不等式log(2)x+4log(3)x+12log(8)x+n·2^(n-1)·log(2^n)x 计算：1/[log(2)3]+1/[log(5)3]=? log(3)1+log(2)根号2+lg1000 计算：8^(1-log(83))(27^(2/3))-log(32) 关于log的题如果log(x)+log(x+3)=1那么x等于多少? log(根号2-1)(3 求值 log【9(下标)】3+log【 9（下标）】27 log【2】（1/2）- log【1/2】2 (log(2)9+log(4)1/9)乘以(log(3)2+log(9)0.5) 括号里是底数.计算这道题.
